Title: A method for producing alternating electric power in a magneto-hydrodynamic generator
IPC: H02K44/08
Filed: 1964-04-15
Abstract: 1,013,028. Generators operating by electromagnetic interaction with fluids. E. BROCHER. April 15, 1964 [April 16, 1963], No. 15526/64. Heading H2A. A magnetohydrodynamic generator comprises at least two tubes 1, 2 connected at one end through a distributer 5 to tanks 8, 9 which contain the working fluid (seeded combustion products) at high temperatures but with the fluid in one tank at a pressure of 2 to 50 times that of the fluid in the other tank. In operation, connection is made alternately to each tank so that a shock wave is induced to produce a higher temperature band of gas in each tube alternately which generates a train of voltage pulses between the respective electrodes 10, 11 or 12, 13. An alternating output voltage, having a frequency determined by the speed of operation of distributer 5, is obtained by combining, either by direct connection or through a transformer (Fig. 3, not shown), the half waves generated at each pair of electrodes. In a modification, for closed cycle operation using seeded rare gas as working fluid, a second distributer connects the downstream ends of the tubes to heat exchangers which are connected to the supply tanks, Fig. 2 (not shown). By employing additional pairs of tubes polyphase outputs may be obtained and the Hall effect may be reduced by segmenting the electrodes.

Title: Improvements relating to electric rotary converters
IPC: H02K47/08
Filed: 1926-06-21
Abstract: 276,467. Townend, R., Juhlin, G. A., and Metropolitan-Vickers Electrical Co., Ltd. June 21, 1926. Rotary converters; commutating poles and windings.-The series field winding of a rotary converter is fed from a separate exciter, of which the field magnet is excited by a current proportional to the main current of the converter, but of which the sense remains constant when the sense of the main current changes. Auxiliary interpole windings may be provided by means of which the interpole excitation per ampere of line current may be changed when the converter changes from normal to inverted operation. The converter 11, Fig. 1, is provided with a shunt field winding 20, an interpole winding 15, and a winding 21 supplied from an exciter 23. The field 26 of the exciter is connected across a resistance 16 in the main continuous-current circuit through a reversing switch 27 which may be operated by a reverse current relay. An auxiliary interpole winding 24 in series with the winding 21 acts in opposition to the interpole field in normal operation, but during inverted operation, the current in the winding 15 is reversed, so that the windings 15, 24 assist each other. If a different degree of compounding is required during inverted operation, one contact of the reversing switch may be connected to the resistance 16, as shown by the dotted line, instead of to another contact of the switch. In a modification, the exciter field winding is in two portions wound in series opposition, and one or both portions may be provided with short-circuiting switches actuated when the operation of the converter is reversed. In another modification. Fig. 4, shown as applied to two converters 11, 11<a> connected in series on the continuous-current side, the exciter 23 has a shunt field winding 32 and two opposing windings 26<c>, 26<d> in series with a resistance 31 in the main circuit. The main pole winding 21, 21a of the converters are connected in parallel- .across the exciter brushes. Shunt windings are omitted as the exciter is given a compound characteristic. The auxiliary interpole windings 24, 24a are connected in series with one another and with a contactor 34 across the exciter brushes. In normal operation, the winding 26d is shortcircuited by a contactor 30 and the contactor 34 is open. For inverted operation, contactor 34 is closed so that the interpole windings 24, 24a assist the main interpole windings 15, 15a, and contactor 30 is opened whereby the exciter field winding 26d comes into operation and overpowers the effect of the winding 26<c>. In a modification, the auxiliary interpole windings are connected in series with the winding 26d and resistance 31 so as normally to be short-circuited by the contactor 30.

Title: Improvements relating to stop motions for machines for treating yarn, thread or the like, such as reeling, winding, doubling and twisting machines
IPC: B65H63/02
Filed: 1922-06-06
Abstract: 200,663. Wilson, T., and Wilson, A. June 6, 1922. Stop-motions.-In a stop-motion for machines such as those for reeling, winding, doubling and twisting yarns, a thread detector 1, Fig. 9, on breakage of an end actuates a latch 5 normally supported by a plate 4 and causes it to fall into engagement with an axially-movable rotating worm 7 secured to the spindle 8. The engagement of the latch 5 with the worm 7 causes the spindle 8 to move endwise, and through the action of a similar axially-movable worm to release the friction drive of the machine and apply a brake. The stop-motion is automatically resetby the groove of the worm 7 raising the latch 5 until it is on the flat portion 7a and is again engaged by the lower edge of the supporting-slot in the plate 4; the spindle 8 being then free from constraint, is moved back to its original position by a spring 8<a>, Fig. 2. If the machine is re-set for starting while yarn is absent from one of the detectors, members 35 on a spindle 34 operated from the foot-board are provided to cause the detectors to swing back and release the corresponding latch 5. A latch and axially-movable worm are provided to form a measuring stopmotion acting as above described when a predetermined length of thread has passed, e.g. in a reeling-machine, the usual bell wheel 26, Fig. 4, is actuated by a worm 28 on the swift axle 29 and a projection 30 is arranged to move a lever 31 which releases a latch 33 from engagement with a plate 32 and allows the said latch to contact with a worm such as 7.
